Title: Perpendicularity measuring instrument
Inventor: OSHIMA MASAO
IPC: G01C9/18
Filed: 1985-10-25
Abstract: PURPOSE:To perform measurement in a short time without being influenced by a wind by fixing a linear body on a point of the base of a hollow bar-shaped body and fitting a float on the other end of the linear body. CONSTITUTION:The linear body 2 is fixed on the point 7 of the base of the hollow bar-shaped body 1. The float 3 is fitted on the other end of the linear body 2 and the linear body 2 is fixed on the point 7 so that the float can be freely swayed. Then, in order to enlarge the buoyancy of the float 3 from the point of measuring accuracy, etc., when the hollow bar-shaped body 1 is filled up with gas, the specific gravity of the float 3 is made lighter than the gas and when the hollow bar-shaped body 1 is filled up with a liquid, the use of water which is inexpensive and easily supplied is proper. Further, a transparent plate 4 is provided to the upper end part of the hollow bar-shaped body 1 and a point where a perpendicular line set up from the point 7 where the linear body 2 is fixed is to pass is indicated clearly on the plate 4 and the perpendicularity of an object to be measured can be easily estimated. Accordingly, since this instrument utilizes the buoyancy, it does not take a time until the float 3 tops and the linear body 2 and the float 3 are surrounded by the hollow bar- shaped body 1 and the accurate measurement can be performed without being influenced by the wind.

Title: Device for supporting transformer lead wire
Inventor: SHIRANE TAKASHI
IPC: H01F27/28
Filed: 1984-11-14
Abstract: PURPOSE:To enable the size between the transformer winding and the tank wall to be reduced by providing, on the portion for supporting a lead wire, a shielded wire having the same potential as the lead wire, disposing a plate for supporting the lead wire between the shielded wire and the lead wire, and supporting these as one body by tightly binding them. CONSTITUTION:A shielded wire 10 electrically and mechanically connected with a lead wire conductor 2 consists of a shield wire conductor 11 and a cover ing 12. On the other hand, a plate 5 for supporting the lead wire is disposed in the space between the shield wire 10 which is formed by curving the lead wire 1, and the shield wire 10 and the lead wire 1 are rightly bound with an insulating string 6 thereby to be supported. Since the shield wire conductor 11 has the same potential as the lead wire conductor 2, only some equipotential lines curve into the space between the lead wire 1 and the shield wire 10 be tween which the lead wire support plate 5 is sandwiched. Thus, the electric field is reduced in a wedge-shaped gap formed between the lead wire 1 and the shield wire 10 and the lead wire support plate 5, so that the dielectric strength between the lead wire 1 and support metal fittings 7 improves.

Title: Photo interrupter
Inventor: MURAKAMI TETSUYA
IPC: H01L31/12
Filed: 1991-09-19
Abstract: PURPOSE:To enable the replacement and the mounting of an optical element and to reduce the size of an optical element by using a ferromagnetic material for a part of the optical element and a magnet for the case, at least a portion thereof holding the optical element, in fabrication. CONSTITUTION:A ferromagnetic plate 8 is stuck on the whole surface of an optical element 1a, and a case 2a is fabricated using a magnet. Thus, by using a magnet to secure the optical element and the case, a space to which adhesive is to be applied becomes unnecessary, only a little space being required for optical axis adjustment. A nickel plate, for example, is preferable for a material of the ferromagnetic plate 8. Thus, fixing an optical element and the case 2a by use of magnetic force provides a smaller photo interrupter such that the replacement and mounting of an optical element is easy.

Title: Separator for lead storage battery
Inventor: HAYASHI TOSHIAKI
IPC: H01M2/16
Filed: 1990-09-07
Abstract: PURPOSE:To increase the elasticity, and furthermore, to improve the high rate discharge capacity of a sealed type lead storage battery using a cellulose fiber by using a mercerized cellulose fiber to the storage battery. CONSTITUTION:A polyester fiber, a mercerized cellulose fiber, and silica powder are mixed and formed to manufacture a mat-form separator. Since the mat-form separator including the mercerized cellulose fiber in a battery using such a separator allows a large deformation to the pressure in the thickness direction, and has a high adhesive property with the electrode plates, the high rate discharge property is improved. But since a deterioration of the separator is generated and a permeation short-circuit of the separator is generated early relatively, the mixing ratio of the mercerized cellulose is preferable to be about 1 to 20%.

Title: Method for drying metal
Inventor: TAKAHASHI KENICHI
IPC: C23G5/036
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of nonuniformity and blot during drying, which may cause undesired appearance of the product, to control oxidation and discoloring during storage, and to maintain good appearance of the product by subjecting a substrate to surface treatment or washing treatment, then treating the treated surface with an aqueous solution containing tolyltriazole and further drying the resulting surface without washing with water. SOLUTION: When washing is carried out, the aqueous solution or the rinse water containing an amount of 0.1-50 ppm of tolyltriazole is used. Though washing time depends on the kind of metal to be treated, shape and washing method, the practically suitable washing time is in the range of 10-600 sec. Though the treatment temp. is also not especially restricted, the suitable temp. is room temp. Moreover, preferable treatment temp. from the viewpoint of drying efficiency is a temp. more than 80 deg.C, thereby more excellent appearance of the product can be obtained. The suitable additive which may be added into the aqueous solution containing tolyltriazole so as to improve the hydro- extraction, is an alcohol or an ether having a boiling point or a decomposition point more than 200 deg.C.

Title: Vertical magnetic recording medium
Inventor: KITAGAMI OSAMU
IPC: G11B5/716
Filed: 1984-11-15
Abstract: PURPOSE:To form a thin soft magnetic underlying layer and to improve the flexibility of a recording medium by forming said underlying layer of a thin Co-Fe film. CONSTITUTION:e thin Co-Fe alloy film having large saturation magnetization is adopted for the material of the soft magnetic underlying layer of a multi-layered vertical magnetic recording medium. The Co-Re alloy has fairly larger saturation magnetization then the satura tion magnetization of 'Permalloy(R)' and Co-base amorphous material and consequently the film thickness of the soft magnetic underlying larger of the two-layered film medium can be decreased. The flexibility of the magnetic recording medium such as flexible disk and magnetic tape is improved. The Co-Fe alloy has a small anisotropy constant in an ade quate compsn. ratio and has therefore a small anisotropic magnetic field and large magnetic permeability. The compsn. of a vapor source changes in the case of forming continuously the underlying layer consisting of 'Permalloy(R)' for a long period of time by vapor deposition and therefore the underlying layer having the consistent quality is not obtainable with the underlying layer formed in a initial period and the underlying layer formed after lapse of some time. The Co-Fe alloy has a small compsn. flucuation and yields the underlying layer having the stable quality in the above-mentioned respect. The substrate temp. may be about 150 deg.C in the case of forming the underlying layer. The selection range for the substrate is thus widened.
